The reaction of [(η5-C5Me5)2Mo2(μ3-S)4(CuCl)2] 1 with Na2S in MeCN produced a trinuclear cluster [(η5-C5Me5)2Mo2(μ3-S)(μ-S)3(CuCl)] 2. 2 crystallizes in the monoclinic system, space group P21/c with a = 15.563(3), b = 8.9547(18), c = 17.846(4) , β = 101.29(3)o, V = 2438.9(9) 3, Z = 4, Dc = 1.878 g/cm3, T = 193(2) K, C20H30ClCuMo2S4, Mr = 689.60, F(000) = 1376, μ(MoKα) = 2.335 mm–1, S = 1.050, R = 0.0305 and wR = 0.0688 for 4033 observed reflections with I > 2σ(I). In the structure of 2, one [(η5-C5Me5)2Mo2(μ-S)2S2] moiety and one CuCl unit are assembled into an incomplete cubane-like [Mo2S4Cu] core framework, in which the Cu center adopts a distorted tetrahedral geometry coordinated by one μ3-S atom, two μ-S atoms and one terminal chloride. The two Mo…Cu contacts are 2.7519(7) and 2.7689(8) , respectively. 相似文献
